How to find the area of non right triangle

We find area of a non triangle by remembering the three combinations of AreaΔ = ½ ab sin C

Step-by-step explanation:

Can be expressed using the lengths of two sides and the sine of the included angle. AreaΔ = ½ ab sin C.

You may see this referred to as the SAS formula for the area of a triangle.

Where the angle is snug between the two sides and A is the top vertices, we usually enter the the adjacent AB BC lengths then sin. = ½  ac sin B  (left angle) and not AreaΔ = ½ ab sin C. (the right angle)

But when we have the angle at B the left side of the triangle we have to rearrange, and to do this we can make a map and draw the triangle out in bold below.  with equation for AreaΔ = 1/2 ac sin B

                                             A      Top side angle

                      7cm    = c    /        \   b

right side angle  30     B     _     C   left side angle

                                   8cm = a

First we recognize aA  bB and cC is opposite one another. and can ignore the lines AB BC AC and focus on the equations.  

B = 30 degree  BA = 7cm   BC = 8cm

AreaΔ = 1/2 ac sin B  eg) 30 degree angle at point B

a = 8cm c=7cm 1/2 = 8*7 sin 30  = 1/2 56 1/2 = Area ΔABC = 14cmsq^2

Therefore with sin B if given an area we find 14cm  is 1/2 1/2 of 56 the sin.

C = 1/2 cb sin A

or sin a given an area, it will always be the opposite to the ABC vertices A= a(opposite line) B= b (opposite line)and C = c (opposite line)

And that is how you remember how to find the area. The opposite line that is missing for A is the base so if that is missing we do the first equation.

If the right side b line is missing we do the second equation given in the example.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
